Each hash stored in the hash-table is over the corresponding executable CRO0 hash-table.
CRR0 files are usually stored under "romfs:/.crr/". The end of the file is aligned to a 0x1000-byte boundary with 0xCC bytes, however the beginning of the padding is the first two text tags from the process NCCH plain region.
